   ElixTechs identity: navy #03045E, blue #0077B6, cyan #00B4D8, sky #90E0EF,
   ice #CAF0F8 · IBM Plex Sans / Plex Mono / Plex Sans Arabic · square corners,
   1px grid lines, mono eyebrow labels.

   - Components use role tokens (--ink, --muted, --label…), never the ramp.
     Roles were picked for WCAG AA: cyan (#00B4D8) is a fill, never text on a
     light ground (2.4:1); labels on light use blue (4.9:1 on white).
   - Dark scheme = :root[data-theme="dark"] (set by elx-theme.js before paint),
     with the OS media query as the no-JS fallback.
   - Layout uses logical properties throughout, so /ar/ (dir="rtl") mirrors
     without overrides; the few [dir="rtl"] rules are typographic.
